Application filed 16,

This invention relates to time lock mech the bolt control is held in holding relation by oppositely movable parts so that shoclcs or jars tending to move one of said parts 1n a given direction will also tend to move an oppositely movable part in the opposlte direction for maintaining the holding eilect of said holding means; further, to provide oppositely movable control parts for the holding means movable in opposite directions for effecting the positioning of the holding means; further, to so interconnect said control parts that movement of one oi them in a given direction will cause movement of a11- other of them in the opposite direction; further, to provide'oppositely movable hold-, ing parts movable in opposite directions for effecting the holding of a bolt-works element to maintain the bolt-works in locked relation; and the invention will be further readily understood from the following de-. scription and claims, and from the drawings, in which latter: r

TIME-LOCK MECHANISM.

1924. Serial No. YB/771.

Fig. 9 is a. detail in cross-section, taken on the line 99, of Fig. 1.

The door may be that of any suitablesafe oi any ordinary or usual construction, such as a burglar proof sate, havmg an integral body, or a body comprising steel plates, or

be a vault body, or of other suitable structure. The door may be a so-called round door, or the door may be of other suitable form or other desirable structure.

Any suitable bolt-works may be employed in connection with the door for locking the same, and may comprise any suitable control means for maintaining the same in locke d relation. We have exemplified only a portion of such bolt-works as a slide 12, nastanced as a control-part of the bolt works, although this control-part may be of any other desirable structure or have any other desirable movement. We have exemplified this control-part as having slots 13, through which shoulder-bolts 14 extend, the shouldering 21, which is secured tothe door by screws 22,- received through the rear wall of the casing and threaded into the door, resilient washers 23, for instance of rubber, being located between the casing and such rear wall to cuslnon the tune mechanism inorder to no door. of the safe is exemplified at avoid detrimental ell'ect thereon by shocks".

or jars towhich the safe or the door may be subjected. i

The casing is provided. with a- .door 525,

closed or locked in suitable manner, and'having a transparent insert 26 .thereiinthrough which the dials of the time be viewed.

,The holding means for the slide areexc mechan-ism 'may emplilied as comprising oppositely acting latches 27, 28, shown located 011 levers 29,

30, provided with pivot-flanges 31, 32. These pivot-flanges rotate about a stud 38 of a stud-piece 3st. A screw Sop-asses through a washer 36 and the stud-piece, and is l threaded into a hanger 37 of a plate 38 for holding the washer, the stud-piece and the plate securely together, and permitting swinging of the levers about the stud-piece. The pivot-flanges are shown reduced in thicknesswith relation to the latches, so as to place the latches in the same plane. The

lever 29 vcomprises an arm 41, and the lever 30 comprises an arm 42.

The plate 38 is secured to the inside of thewall 13 of the casing. The bottom wall 44 of the casing is provided with a slot 45,

the'relative arcuate movement of the arm and the right line movement of the bar.

The opposed movements oithe bars are effected in the present instance by providing disks 56, 57, rotatable on shoulder screws 58, 59, secured to theplate 38, and providing the disks respectively with pins 61-, 62. The pins 61 are located in holes 63 of the bar 52, and thepins 62 are located in holes 64; in the bar 51. The respective pins are on opposite sides of the disk, so that rotation of the disks in either direction moves the bars lengthwise in opposite directions. Each of the'disks is provided "with a spacing-hub 65, and the bars are positioned in thespace between the disks andthe plate 38, respectively above and below the hubs. v

The means exemplified for actuating the bars is a time mechanism, consisting of a series of time-clocks 7 1, 72, 73, such as are used in time lockdevices in sates. Thetimeby-any one or more of thepins75,'coacting clocks are provided with dials 74, having thereon knock-out pins 75. The dials are provided withsuitable graduations of a suitable number ofhours, for instance seventytwohours, and are arranged to be set and to. be rotated by suitable clock movements therein, which maybe wound in suitable manner, not necessary to be further describedas the same are well-known. 7

Suitable hands76 are provided, with relation to which the dials are rotated to indicate the number of hours to expire before the time mechanism is moved into releasing relation, and 'at which the" safe is to be opened. The releasing movement is efiected:

with one of thebarsconcernedin effecting release ofthe holding means for the bolts.

The springof any one of the time moveworking condition, although ordinarily all of the time devices combine to effect such m m nt- The movement of the bars is exemplified as eilectedby means of levers 78, pivoted on shoulder-screws 79, one end of the levers being within range of the pins on the respective dials, and the other end of the levers being within range of shoulders 80, shown as the end walls of slots 81 in the bar 52, in which said other ends of said levers are received.

The latches are normally urged into latching relation by means of a spring 82, received about a pin 88, fixed to a lug 84, extending from the plate 38., the spring being located between said lug and a lug 85 fixed to the bar 51, for normally urging the bars in directions to effect'holding positions of the latches.

'The slide 12 is represented as normally retracted by a spring 86 for release relation of the bolt-works, tberespective ends of the spring being secured to said slid-e and to the safe-door. The slide has a rack 87 with which a pinion 88 meshes, the pinion rotating on a stud 89 ext-ending from the safedoor. The pinion is releasable from the stud andis provided; with a handle 90 for rotating thesame.

When it is desired to lock the safe, the

time-clocks are wound and the disks turned to set the same'for the beginning of the period oit'ilocked relation of the door, whereby the knock-out pins arespaced from the knock-out levers, as shown in Fig. 1. The

latches are thereby also placed in engagingpositions. The slide 12 is then, moved for placing its-holding arm 17 in latching relation. with the latches, which is effected by movement of the. slide by means of the pinion 88. Theengaging portion of the arm is provided with a sloping face 92 coacting with the sloping faces 93 of the latches for It the safe or the door or the timing mechanism should, during such locked relation, be sub ected to any shock or Jars, it

will be readily seen thatany shock or jar tending to move any part of the time-lockcontrol means for the bolt-works in one direction will also. tend to move an opposite bolt-works control throughout the locked relation of the safe. Any shock or air which might tend to create an unlocking movement in one of the opposing pa "ts, either in the holding means or in the actuating means therefor, is transmitted as a. shock or jar in locking direction upon the corresponding opposing part. The elements ofthe pairs of opposing parts act as opposing elements movable in opposite directions for maintaining a locked relation of the bolt control mechanism.

The danger of effecting opening of the door or release of locking relation in any of the mechanism is, therefore, minimized or avoided.

Having thus fully described our invention, whatwe claim as new, and desire to secure by Letters Patent, is:
